12.5 - file size on Vimeo preset

Hey, guys.

I've been away from videoland for a while and need a sanity check. Updated to Resolve 12.5 (very nice) and have been experimenting with delivery based on the Vimeo preset, 720p / h.264.

I've only changed the bitrate settings. Whether I go with the defaults, 10k bitrate max, use the "Least" preset, or in my final case set the max bitrate to 5k, the file size seems about the same. 10k max is around 13.5 megs per minute, as is, curiously, the "Least" setting. I finally set max bitrate to 5k, which gave me around 12.5 megs per minute.

For a 720p h.264 video, does this seem about right, or is it on the large side for the given settings?
